Contact Summary: 

Mr. Lowell Miles was contacted on behalf of the U.S. EPA to update information provided 

in the 1993 EPA Reinforced Plastic Composites Screening Survey submitted by Miles Fiberglass 

& Plastics, Inc. for their facility located in Oregon City, Oregon. In response to my questions Mr. 

Miles indicated the following; 

The facility produces products for both corrosion resistant and non-corrosion resistant 

apphcations. The non-corrosion resistant products produced by the facility are tub & shower units 

and components of recreational vehicles. The facility also produces interior components for 

recreational submarines which often come in contact with salt water. The conosion resistant 

products produced by the facility include industrial tanks fot waste water treatment, chemical 

processing & storage, and food processing. 

The facility uses the spray lay-up process in the fabrication its non-oorrosion resistant 

products. The dicyclopentadiene (DCFD) and isophthalic polyester resins used in the fabrication 

of these products contain approximately 37.9% HAP by weight and 49.0% HAP by weight, 

respeaively. The faoility uses each of these resins equally (on the basis of tonnage of resin 

consumed) during the fabrication of non-corrosion resistant products. The facility uses the vacuum 

bagging process in the fabrication of approximately 45% (on the basis of tonnage ofresin consumed) 

of its non-corrosion resistant products. 

The facility uses the spray lay-up process in the fabrication its corrosion resistant products. 

The polyester resins used in the fabrication of these products contain approximately 45-50% HAP 

by weight 

The only HAP initially present in the polyester resins used by the faciUty is styrene. No 

additional HAP is added to the resins during the fabrication processes with the exception of small 

amounts of HAP that may (or may not) be present in initiators, promoters, and/or catalysts added 

to the resins. None of the resins used by the faciUty contain a vapor suppressant.

The facility uses spray lay-up to apply several pigmented polyester gel coats which contain, 

on average, approximately 36.5% HAP by weight (34% styrene and 2.5% methyl methacrylate). 

While the average methyl methacrylate (MMA) content ofthe gel coats is approximately 2.5%, this 

does not imply that all ofthe pigmented gel coats contain MMA. No additional HA? is added to die 

gel coats during the fabrication process with the exception of small amounts of HAP that may (or 

may not) be present in initiators, promoters, and/or catalyses added to the gel coats. 

All of the mixing conducted at this facility is done inside a 300 gallon mixing tank. The 

mixing tank is covered and no visible gaps exist between the cover and the rim of the mixing tank. 

The facility does not actively (force) vent emissions from the mixing tank by applying a vacuum to 

the mixing tanlc There are no openings in the cover ofthe mixing tank other than a single slot for 

the mixing shaft. This slot is designed to allow tiie shaft to sUde back and forth thereby adjusting 

the position ofthe mixing blades. By constantly adjusting tiie position of tiie mixing blades, the 

amount of heat produced by the friction between the mixing blades and the resin system is increased 

or decreased as necessary to maintain the desired temperature ofthe resin system. A thermostat 

constantly takes a reading ofthe temperature ofthe resin system and automatically adjusts the angle 

of the blade to increase or decrease friction and thereby keep tiie resin system at a constant 

temperature. The temperature of the resin system used by the facility is important because the 

temperature of the resin system is directly related to the viscosity of the resin system. Without 

maintaining the resin system at a high temperature (and low viscosity), the high viscosity ofthe 

filled resin system used by the facility would prevent the successful tiansfer ofthe filled resin system 

from the mixing tank to the spray guns using closed lines. Successful appUcation of tiie fiUed resin 

system through the spray guns to the open molds would abo be prevented.
